DISTRIBUTOR SPOUT MEGHANISM 3 Sheets-Sheet 5 Filed March 20. 1959 Patented June 3, 1941 UNITED STATES PATENT OFFICE Y 2,243,840- msrnmnfronsrour MEcHANI-sivr Louis Delivuk, Spokane, Wash. Application March 2o, 1939, serial Ne. 262,922 e claims. (cifras-23) This invention relates to improvements. in remote control mechanism for the distributor spouts ofgrain elevators.

The `usual form of a grain elevator consists broadly in a plurality of grain bins with a lower work floor, an upper distributor floor and a distributor spout mounted to be advanced into selective positions to deliver grain intothe ingress ends of the usual gra-in pipes that convey the grain to the several bins. The means for controlling the distributor spout has always been located in a position accessible to the operator on the work oor, and of course the operator thus located is in a remote position below the distributor floor and cannot see the action of the parts he manipulates. Further, indexing wheels, in cableconnection with the spout often become inaccurate due to cable slack and settling of the structure and other causes, and considerable time is wasted when it becomes necessary for the operator on the work oor to ascend to the distributor oor to inspect the spout mechanism and make adjustments to correct inaccurate operation. Lack of registry of the distributor spout with the grain pipes causes losses and wastes that cannot be observed from the workfloor.

The/se, and many other defects of the present systems which it is unnecessary to detail, constitute the motive for the improvements which comprise my invention. Among my objects, it is a feature of the invention to restrict the spout advancing means, whether cable-indexed or not, to the mere function of advancing the distributor spout into or toward an estimated position of registering delivery relation to the selected grain pipe, and to provide'means whereby an accurate and positive delivering registry may be insured and maintained irrespective of any inaccuracy of the advancing means.

A distributor spout is seldom advanced consecutively into delivery registry with successively disposed grain pipes in any order of uniformity, but on the contrary it is advanced in either of two opposite directions, from delivery relation with one pipe, to a like relation with a pipe remote from the pipe it was last Vregistered with,

and then back again to intermediately disposed any improvedv means whereby the delivery end of the distributor spout is automatically connected with the grain: pipe, when. brought into registering delivery therewith, in such a manner as to prevent dust from escaping into the super-structure above' the distributor floor, in which the distributor spout mechanism is housed.

In present constructions the distributor spout is structurally centered to be rotated about a fixed-axis and is sustained by a main or major support in such centered position. Now it is an object ofmy invention to provide the delivery end of the distributor spout with a minor support which will maintain the delivery end in aV which will be more fully described in connectionv with the accompanying drawings and which will be more-particularly pointed out in and by the appended claims.

With reference to the drawings, I will rst describe a usual elevator structure, and while I have herein, and also in the claims, referred to a grain elevator, it will be understood that the device of my invention is equally adapted to elevators of like character wherein coffee, rice and similar material is handled, hence, I do not wish to be limited to grain elevators.

Referring very generally to Figs. 1 to 5, an elevator is shown and generally designated at I, the same having grain or like bins 2 to 9, and what is called a machinery well I0. The elevator has a lower work floor II, and an upper distributor floor I2, which, as will now be clear, are remotely separated by the height of the: elevator which of course varies in accordance with the capacity thereof. Extending lengthwise of the machinery well I5 are the up and down legs i2 and i3, respectively, of the usual elevator mechanism which need not be described in detail and which has a suitable intake in a Wheat receiving pit I4. The legs I2 and-I3 extend upwardly 1in well Iii, and into the spout house I5, wherein the endless conveyer (not shown) in the legs I2 and I3 dumps the grain into a head hopper i5 that discharges into a distributingspout generally indicated at I1, and which will later .be described more in detail. A chute i3 carries the dust from the hopper I6.

Agrain delivery or bin pipe is provided for each bin andvsaid pipes are designated at IIB to and said pipes have ingress ends 21 to 34, opening through the distributor oor I2, as shown inFigs. 6 and 7, and said ingress ends are arranged in a definite order which, asshown, is in a circular formation about the axis of rotationof spout L1. Thus, spout I1 can be moved or rotatively advanced into registered delivery relation to any one of said ingress ends 21 to 34. i As will be seenby reference to Fig. 7, thel up- V perorintake end of spout I1 is structurally pivoted or centered to rotate about a iixed vertical axis by being sleeved or. telescoped about hopper to provide a permanent dust proof connection It. A main or major support for said spout I1 usually consists of a rod 36, which may be suitably iixed in a boss 31, secured to spout I1 at its upper end, the lower end 3B being socketed 1in a bearing 39 secured to the distributor floor I2, as at dii. A sheave 4I is xed to rod S6, anda cable 42 is trained about, and if desired anchored to said sheave, the limbs of said cable extending over pulleys 43 (Figs. 1 and 2)y andl down the machinery well I0, and about a sheave M xed to a sleeve d5. Sleeve :i5 is rotatable on a stub shaft 46, mounted on a slidingV block 'i that is slidable in a guide 43, mounted on any stationary part such as the upleg IfZf. A weight 45, connected with said block by'a cable 55, normally acts to maintain vcable 2 -under tension.

Means, which Vmay be an indexed means, is employed, as shown, for operating said cable fifi, and may consist of a manually operable index .wheel 5I having a hub 52 xedly mounted onY said sleeve i5, and Vhaving an index finger 53. An arcuate index strip 54 is xedly mounted at .55 `on leg i2', and has index numbers 2 to 9, corresponding :to the numbers of bins 2 to 5, orf-eight in number.

The'foregoing is a usual construction of grain elevator except that the spout I1, as shown, is

not-tiltable to lower its discharge end tov/ard orv into Vthe ingress end of a grain pipe, buton the.

contrary rotates in dustproof engagement about a fixed vertical axis, of which the axis of rod 36 is the center, andA the substantially horizontally disposed discharge end of spout I1 is maintained ini alsubstantially horizontal position, as will later appear.

wheel 5I as the indexed means for actuating or advancing spout I1, I do not wish to be limited thereto, as any suitable remote control means for performing this function would be within the scope of my invention.

Reference will next be made to what more particularly constitutes the subject matter of this invention, and I will refer to Figs. 6 to 10.

The discharge end of spout I1 is preferably in the form of an elbow and is formed of rather heavy material such as cast iron and is indicated at 56, and this end outwardly telescopes the tapered end of t'he angularly disposed or inclined main body of the spout I1, and is made oi heavy material because of the Wear imposed by the grain. The extreme terminal or downwardly facing discharge end 51 is disposed slightly above the distributor oor I2, and because of a minor support which I shall presently describe, this extreme terminal is always maintained in a horizontal plane of movement and the horizontal position of the extreme end 51 therefore never changes from the position shown in Fig. 6. Thus, I avoidthe tilting movementof spout I1 that has been heretofore .necessary in order to make delivery connection with the grain pipes. .Because the spout need not be tilted, I thereby avoid making it in telescoping sections and am able to make the spout I1 wholly inextensible and non-contractible throughout its length.

The ingress ends of all the grain pipes I9 to 26, instead of being flared or-having funnel ingress ends, are, on the contrary, of the normal diameter of the main bodies of the pipes, and are also of` substantially the same internal diameter as the spout I1, `thereby effecting a material saving in construction, and as all are identical in form and function, only one need be described in detail. Thus, it will be seen that grain pipe 3i), which delivers to bin 1, yand as shown in Fig. 6, extends slightly above the level of floor I2 to form an ingress end 30. Y

I will next describe aV novel means whereby the extreme terminal 51 of spout I1 may automatically make aV substantially dustproof connection with an ingress` end 36', when brought into registry therewith, vand how such connection is automatically dis-established when saidspoutis advanced out of'registry with said ingress end.-

Said'feature is embodied in a flexible coupling which may be applied to either pipe entity, but

r. vV'While" I'have shown the cable'42, and index 75 which I preferably apply to the discharge end 55 of the spout. As shown, said coupling consistsofV a ring of -ilexible material, such as rubber, as indicated at 58,7the'upper portion, as shown, lbeing rather thick and the lower projecting Aor depending flange 55 being of substantially reduced thickness to increase its flexibility. Said flange 59, as shown, projects slightlyV below the terminal 51, and the spacingy of the latter from the top of end 30 permits said ange 59 to ilex inwardly throughout its advancing peripheral portion, as the. spout approaches a position'of registrvwith said ingress end, andl nally assumesthe' telescoping relationship shown in Fig. 6, as will now be clear. While I do not pretend thatfthis Yis an absolute dustproof it, itV is suiciently ,so that only a minor portion of dust wulescape intothespout house. It Will now be clearA how the flexible couplingY isY automatically disconnected `when the spout moves out of reg` istry with the ingress end. -I amtherefore able to provlde a spout which at'all times turns about a vertical axis, without anyV tilting movement,

.and at the same time I make an effective dust proof connection with each ingress end of each grain pipe.

Reference will next be made to what I will term a minor support for the spout I1, and to additional functions which this minor supporting mechanism performs.

This mechanism involves a track that is shaped to correspond with the disposition of the ingress openings, which, in the present construction, is a circular formation, and as shown in Fig. 2, the track, which is generally indicated at A, `has a radius struck from the axis of rotation of spout I1, or in other words, the axis of rod 36, in Fig. 7. The ends B of track A terminate short of a complete circle and the downleg I3 is interposed between the -ends B.

Referring now to a more detailed showing of the track A, and particularly to Figs. 6 to l0, it will be seen that the track is of angle formationlin cross section, one part 60 being suitably fixed to floor l2, and the other part or flange 6I `forming the actual rail of the track. It will also be noted that the track is disposed inside the discharge end of spoutl l1 so that the latter over-hangs and extends radially beyond the track thereby leaving the discharge end 56 free 'toand function, only one need be described in detail.

Said elements of said devices, as shown, are disposed radially inwardly of the track, and are preferably attached thereto, and as shown 'in Figs. 8 to 10, said element includes 'an angle having an upright flange 62 secured to rail 6I, as by means of bolts 63, and a horizontal ange 64,V which rests on floor I2 and which need not be secured thereto unless it is found desirable. On flange 64 `is secured a rail having oppositely disposed inclines orv inclined portions "65 which function vas camspand *an intermediate recess 66, which performs the `function of a register element or keeper. 'Ihese parts are so disposed that if ra radial line were drawnirom. Jdhe axis of rotation ofV spout I1, through Athe axis of rod 36, and intersecting the axis 'of an ingress end, such as 3D', then` such line would pass through the center of the recess or keeper 66. Thus a keeper is associated or provided `for each ingress endand in radial alnement therewith.

Reference will next be made to a means which includes an element that coacts with the keeper element to arrest and retain the spout ina position of registry with an ingress end, and I will now refer to Figs. 6, 8 rand 9. v

A part of thismeans includes a minor .support for .the spout I1, which especially functions to sustain the heavy discharge elbow `56 at a 'uniform elevation above the distributor oor I2 and this part of said means is in the form zof undercarriage which includes al frame having an anchoring por-tion 61 adapted to be secured `=by means vsuch las bolts 68 to a depending 1ug69, which may be formed integral with the Yicast'iron discharge end 56. Said lug 69 has a flange 10 that forms a shouldered `oiset 1I, whereby the I- anchoring .portion 61 .will have a ystructural ycon'- nection with lug 619, vwhenY bolted thereto, to reduce the stress on bolts 68. The frame includes a central portion 12 from which forkedl journals 13 extend in opposite directions. Flanged carriage wheels 13 are rotatively mounted in said forked journals and are adapted to traverse the rail 6I, as will now be clear.

A -guide 14 may be cast on or attached to the carriage frame and may be provided with a removable side 15. This guide has a guideway 16 in which a latch member or bolt 11 is guided and held` to a vertical path of movement, and in its normal retracted position, the lower end 18 of said` bolt may project slightly below said guide. Said bolt 11 is shown reduced at its upper end as at 19, and to insure its descent in said guide I may interpose an expansively acting spring 86 between part and the shoulder 8|, which will normally act to shift said bolt 11 downwardly toward and into the keeper 66, if in practice the action of gravity is not sufhcient. When bolt 11 is lowered to its extreme position, as shown by dotted lines in Fig. 8 (engaging the right hand cam 65), it will engage one of the shifting cams 65, riding up the same, until it reaches notch or keeper 66, whereupon it will quickly descend thereinto and arrest and lock the carriage against pivotal movement and in a position of rest, thereby forming a delivery point register mechanism.

Any suitable remote control means may be provided for retracting said bolt and holding it retracted in the full line position shown in Fig. 8, against the action of spring 86. Except when it is in engagement with a keeper, it is necessary to retract the bolt 11 and maintain it retracted to avoid engagement with successive keepers beyond which it may be desired to advance the spout.

One means shown, and which is especially adapted for this functiombecause of the necessity of remote control, is of an electrical form and may consist of a solenoid 82, mounted in a casing 83, secured to the carriage frame, and having an armature Sri which is movable upand down in the winding, as will be clearly understood. The lower end of the core or armature is enlarged to form a fork S5, not only to limit upward movement of the core butalso to afford a pivotal connection 86 with bolt end 19.

Because the spout I1 never completes a circular movement, I find it convenient to connect thesolenoid to one end of an electrical cord 81, with sufiicient slack to accommodate movement of spout l1, the remaining end being connected with a plug 83 to a convenient socket 86, or one conveniently located. In order to illustrate a circuit, leads Y9H and SI extend from said socket down the machinery Well I0 to a suitably placed switch 92, a source of current being indicated at 93. In Fig. l1 `I have shown the complete circuit in diagrammatic form, the solenoid being indicated at 83 on spout I1, with distributor floor shown at i2, and the Work floor below at l I. The switch 92 is shown in an open circuit position and can be closed by engagement with the terminal 94. However, many changes may be made in the electrical wiring without departing from the invention, and, broadly considered, I claim a remote control for the bolt 11, for the general function as now dened. I

While the operation of my invention may be clear from the foregoing, it will be briefly recapitulated as follows: Y With spout I1, in the Figs. 2, 6 and '7 position, delivering to ingress end 36', the switch 92 would be open and the bolt,11 would be down and in engagement with the keeper in radial relation to ingress end 30. After making this delivery, and assuming that the operator desired to shift the spout l1 to ingress end 21, for instance, he would first adjust switch 92 into a circuit closing position and this would energize solenoid 82, and retract or lift bolt 11 out of engagement with the keeper, and of course the switch would remain closed in order to free the lower end of bolt 11 from the keeper devices located between ingress end 36 and ingress end 21. Otherwise spring 80 would force bolt 11 down again. With the spout l1 now free the operator would grasp index wheel l and turn the same contraclockwise, viewing Fig. 3, until the index 53 registered with number 2 on the dial 54. Slightly before the index 53 reached dial number 2, the operator would know that the bolt 'i1 has passed over the keeper of ingress end 28, and therefore he would open switch 92 to free bolt 11 so that spring 5 could force said boltA downwardly. Hence, the bolt would first engage the cam B5 that it was approaching and would ride up on At this pointit is desired to emphasize the fact that the operator on the work floor-l l cannot possibly see the movement of spout I1, and therefore he will be, in the strictest sense, operating the latter by remote control. Irrespective of the take-up device shown in Figs. 3 to 5, which takes up cable slack as a result of settling of a frame elevator or for other causes, there is always a certain degree of inaccuracy that develops in such a cable indexing means. Hence, it was heretofore necessary to flare the ingress ends of the grain pipes, in addition to tilting the spout, to lower the discharge end into engagement with the dared or funnel intake ends of the grain pipes, to make allowance for such inaccuracy.

However, with my present arresting and retaining devices, it will be clear that a very considerable inaccuracy could develop in the cable indexing means, an inaccuracy of many inches in fact, and still the operator could safely open the circuit after the index member 53 had passed dial number 3, knowing full well that the released bolt 11 would first engage the nearest cam 85 and finally coact with the keeper 66 of ingressend 21, and arrest and retain the spout in registry therewith, even though index member 53 had not yet reached, or had even gone beyond dial number 2. In fact, the engagement of bolt 11. with the keeper of the selected device, could readily be felt by the operator since this engagement alone, and by itself, would prevent any further movement of the spout I1 by wheel 5l, in either of two opposite directions.

Since movement of spout I1 is seldom moved consecutively from one ingress end to another, in any fixed order, but is in the vast majority of instances moved selectively back and forth to variously located ingress ends, it will now be clear why it is ,important to provide bolt engaging cam tracks t5, extending in opposite directions from the centrally disposed keeper, except perhaps at the terminal ends B.

It will now be clear how the flexible coupling 58 will successively and automatically connect itself Vwith and from each ingress end as the spout is advanced in either direction, but as the spout is moved slowly, the coupling will merely ex over the ingress ends of pipes o ver which it does not stop. While I regard this flexible coupling, o r its equivalent, as a very advantageous feature, it will be understood that the device of my invention would be clearly and effectively operable in the absence of this feature.

It will also be Iclear that a Wide variety of exible couplings could be used because the rapidly descending grain in spout l1 would itself act to inate an even less resilient coupling than that shown, or in facteven a non-resilient but flexible coupling, because the grain is in such volume, and because of the graduallyl reduced, diameter of the spout.

It is important to note the fact thatin addition to carrying the bolt 11, and its operating mechanism, the carriage also functions, in an important capacity of maintaining the extreme terminal 51 thereof in a fixed horizontal plane of travel, thereby making itpossible to employ a coupling that can be automatically connected with the vingress ends.

Because of the fact that. the spout l1 is angularly disposed to the vertical vand has only its upper intake end structurally centered and structurally supported, the weight mass is always out of balance and therefore if it were not for the supporting function performed by my carriage at theY discharge end, the overbalance of weight would impose an objectionable torsion on the parts which structurally center the spout.

As the index wheel and cable advancing means is old, it is important to note that any means for advancing the spout in opposite directions would be within the scope of this invention if the operator on the work floor had anymeans of indieating the position of the spout, hence, an indieating means which is also an advancing means is not essential to my invention.

It will now be clear that I have disclosed mechanism which specifically involves the bolt 11 and keeper 66 for arresting Vand retaining the spout y in registering positions with ingress ends, to-

gether with means for rendering said mechanism effective, as by releasing said bolt, or rendering said mechanisml ineffective, as by retracting said bolt.

It is believed that the track and carriage mechanism shown and described is novel as an article of equipment, and I have claimed it as such.

Because of the velocity which the grain attains by the time it reached the elbow 56, I have purposely made the latter of relatively heavy and durable material, as previously stated, and it will be seen that this construction permits lme to mount the carriage 61, the bolt 11 and guide 14 and the solenoid casing 83, containing the solenoid, in fixed relation to this elbow 56. Thus, I provide a self-'contained assemblage which not only avoids the requirement of any connection with vsupport 35, but which, in addition, constitutes-aniaccessory that can readily be applied t0 an old distributor spout having the usual mounting at its ingressV end. With this accessory, it will be understood that the track wouldfalso be necessary in the specic form shown.

It Vwill also be clear that by disposing the track A, radially inwardly of the elbow 56, so that the latter overhangs the track, that I am not only able to mount the track directly upon the distributor floor, without elevating the track, and I t can dispose and connect the carriage with the elbow in' subjacent relationV thereto whereby I obtain a mostadvantageous mechanical efficiency in the supporting relation and greatly facilitate the connection of the solenoid by a liiexible con- `and occupying a single horizontal plane, a distributor spout mounted to Arotate about a fixed axis coincident with the center from which said circularly arranged ingress ends are disposed and 'said spout having a downwardly facing horizonytally disposed discharge end disposed substantially parallel with the plane occupied by said ingress ends and of substantially the same internal diameter as any one of said ingress ends, means for supporti-ng said discharge end at a fixed level of travel and in clearance relation to said ingress ends, means for advancing said spout to dispose said discharge end into direct delivery registry with a selected ingress end, and a flexible annular coupling mounted on said discharge end and having a flange depending below the plane occupied by said ingress ends and the clearance of said discharge end being sufficient to permit said depending iiange to be automatically exed into surrounding dustproof connection with an ingress end as said discharge end is advanced into registry therewith and flexed out of such connection as said discharge end is advanced away from said ingress end.
